'P' Rule to Support Dial Prefix

This rule is for automatic pre-pending the dial string as entered by the user with a specified prefix.
Syntax
Ptnnnn
where t is a single leading trigger character; if t is the first entered digit when making a new call, it
triggers the prepending of a variable-length prefix (as specified by nnnn) in the dial string. The t
character can take one of the following values:
0-9,*,#, 'n' (= any of 1-9), 'N' (any of 'n' and 0), 'a' (any of 'n',* and #), or 'A' (any of 'a' and 0);
Example:
Pn12345: Prepends 12345 to the dial string when the first entered digit is any of 1-9. The triggered di git
is not removed from the dial string.

•ntone is the number of frequency components (0, 1 or 2).
•freq[0] (Hz) is the transformed frequency of the first frequency component (-32768 to 32767).
